The imperative for schools and teachers to understand and teach with a global perspective has been reiterated in Victoria recently with the release of the Victorian Curriculum Reform Consultation Paper (VCAA, 2004). This paper states that, "the purposes of schooling are to prepare students for a world which is global in its outlook and influences." (p.4).

The introductory paragraphs of selected states' and territories' Studies of Society and Environment (SOSE) curriculum statements include and reiterate 'global' in the rationale for teaching and learning. Teaching in SOSE is charged with responsibility for incorporating 'global' into classroom practice. What is the role and place of SOSE in this teaching and how can SOSE teachers be better equipped to teach in a time of internationalisation and globalisation? Are teachers prepared to meet this challenge?

This paper will position the importance of teachers' lived experiences, their capacity to reflect upon these experiences, to their preparedness and competency in teaching 'global education' both within a SOSE classroom and beyond. How can personal critical reflection sharpen the focus for teaching in and to this global world? What are the place of narrative and the lived experiences of teachers in sharpening this focus? The data for this paper is drawn from a self study of the author who is studying a Masters by Research and teaches Social Education and Education Studies at Deakin University.

The paper argues that pedagogy around teaching global education in the classroom cannot be isolated from the teacher's identities, background experiences, which influence and shape their approaches to teaching in a global education curriculum. The methodology in teaching global education needs to be further aligned to teacher narratives and the lived experiences of teachers in order to link local, national and global domains.

The paper will describe how teaching for a 'world which is global in outlook and influences' can be researched by examining a selection of personal stories and lived experiences. The paper will conclude with a draft framework of global education that acknowledges reflection on lived experiences and narratives.

This paper examines rhetorical constructions of ‘reality’ in selected outdoor/environmental education discourses-practices.1 Many outdoor/environmental educators privilege philosophical realism coupled with suspicion towards poststructuralism(s) and deconstruction. From a postlogographic position on language, we argue that producing texts is a method of inquiry, an experience and performance of semiosis-in-use as we sign (and de/sign) the world into existence. This re/de/signed world never represents the ‘real’ world precisely or completely, and in this paper we explore and enact modes of textual (and extratextual) production that struggle to retain a poststructuralist skepticism towards representational claims without falling into antirealist language games. We focus in particular on Deleuzean concepts of ‘rhizomatic’ inquiry and nomadic textuality as enabling dispositions for re/de/signing worlds in which realities and representations are mutually constitutive (rather than dialectically related).

Desktop computers based virtual training systems are attracting paramount attention from manufacturing industries due to their potential advantages over the conventional training practices. Significant cost savings can be realized due to the shorter training-scenarios development times and reuse of existing engineering models. In addition, by using computer based virtual reality (VR) training systems, the time span from the product design to commercial production can be shortened due to non-reliance on hardware parts. Within the aforementioned conceptual framework, a haptically enabled interactive and immersive virtual reality (HIIVR) system is presented. Unlike existing VR systems, the presented idea tries to imitate real physical training scenarios by providing comprehensive user interaction, constrained within the physical limitations of the real world imposed by the haptics devices within the virtual environment. As a result, in contrast to the existing VR systems, capable of providing knowledge generally about assembly sequences only, the proposed system helps in procedural learning and procedural skill development as well, due to its high physically interactive nature.

Background: School playgrounds during break times provide potential opportunities for children to be active during the school day. However, there is limited research on how active children really are during these breaks.

Methods: The CAST (Children's Activity Scanning Tool) instrument was developed, validated, and used to assess the percentages of children engaged in moderate to vigorous physical activity (MVPA) and vigorous physical activity (VPA—a subset of MVPA) in 18 primary schools (children ages 5–12) in rural Australia. Related environmental factors were also measured.

Results: For a school of median size (200 students), 51.4% of boys and 41.6% of girls were engaged in MVPA while 14.7% of boys and 9.4% of girls were engaged in VPA. Levels of engagement in MVPA and VPA were significantly higher during lunch periods than during recess. MVPA and VPA engagement in smaller schools was significantly higher than in larger schools.

Conclusions
: With growing concern about children's physical activity (PA), school playgrounds offer an opportunity to increase children's MVPA engagement especially among girls. Consideration may be given to the lengthening of recess periods in order to increase PA levels. More research is needed to investigate factors affecting PA levels in larger schools.

Generic models of job stress, such as the Job Strain Model (JSM), have recently been criticised for focusing on a small number of general work characteristics while ignoring those that are occupation-specific (Sparks & Cooper, 1999). However this criticism is based on limited research that has not examined the relative influence of all three dimensions of the JSM - job demand, job control and social support - and job-specific stressors. The JSM is the most commonly used model underpinning large-scale occupational stress research (Fox, Dwyer, & Ganster, 1993) and is regarded as the most influential model in the research on the psycho-social work environment, stress and disease in recent times (Kristensen, 1995). This thesis addresses the lack of information on the relative influence of the JSM and job-specific stressors by assessing the capacity of an augmented JSM to predict the strain experienced by managers and professional Australian footballers. The augmented JSM consisted of job-specific stressors in addition to the generic components of the model. Managers and professional Australian footballers represent two very different occupational groups. While the day-today roles of a manager include planning, organising, monitoring and controlling (Carroll & Gillen, 1987), the working life of a professional Australian footballer revolves around preparing for and playing football (Shanahan, 1998). It was expected that the large differences in the work undertaken by managers and professional Australian footballers would maximise the opportunities for identifying job-specific stressors and measuring the extent that these vary from one group to the next. The large disparity between managers and professional footballers was also used to assess the cross-occupational versatility of the JSM when it had been augmented by job-specific stressors. This thesis consisted of three major studies. Study One involved a survey of Australian managers, while studies Two and Three focused on professional Australian footballers. The latter group was under-represented in the literature, and as a result of the lack of information on the stressors commonly experienced by this group, an in-depth qualitative study was undertaken in Study Two. The results from Study Two then informed the survey of professional footballers that was conducted in Study Three. Contrary to previous research examining the relative influence of generic and job-specific stressors, the results only provided moderate support for augmenting the JSM with job-specific stressors. Instead of supporting the versatility of the augmented JSM, the overall findings reinforced the broad relevance of the original JSM. Of the four health outcomes measured in Studies One and Three, there was only one - the psychological health of professional Australian footballers - where the proportion of total variance explained by job-specific stressors exceeded 13%. Despite the generally strong performance of the JSM across the two occupational groups, the importance of demand, control and support diminished when examining the less conventional occupation of professional football. The generic model was too narrow to capture the highly specific work characteristics that are important for this occupational group and, as a result, the job-specific stressors explained significantly more of the strain over and above that already provided by the generic model. These findings indicate that when investigating the stressors experienced by conventional occupational groups such as managers, the large amount resources required to identify job-specific stressors are unlikely to be cost-effective. In contrast, the influence of the more situation specific stressors is significantly greater in unconventional occupations and thus the benefits of identifying these non-generic stressors are more likely to outweigh the costs. Studies One and Three identified strong connections between job-specific stressors and important characteristics of the occupation being studied. These connections were consistent with previous research and suggest that before attempting to identify job-specific stressors, researchers need to first become familiar with the nature and context of the occupation. The final issue addressed in this thesis was the role of work and non-work support. The findings indicate that the support provided by supervisors and colleagues was a significant predictor of wellbeing for both managers and professional footballers. In contrast, the level of explained strain accounted for by non-work support was not significant. These results indicate that when developing strategies to protect and enhance employee well-being, particular attention should be given to monitoring and, where necessary, boosting the effectiveness of work-based support. The findings from this thesis have been fed back to the management and sporting communities via conference presentations and peer-reviewed journals (refer pp 220-221). All three studies have been presented at national and international conferences and, overall, were well received by participants. Similarly, the methods, results and major findings arising from Studies One and Two have been critiqued by anonymous reviewers from two international journals. These papers have been accepted for publication in 2001 and 2002 and feedback from the reviewers indicates that the findings represent a significant and unique contribution to the literature. The results of Study Three are currently under review by a sports psychology journal.
